Procurement Notes
Verify the current lifecycle status before procurement, as the BD5451EFV-E2 is marked as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors, noting that stock levels may be limited or unavailable. Ensure compliance with RoHS requirements and moisture sensitivity handling protocols during storage and assembly processes.
Selection Notes
Select this component for applications requiring a 30 W Class-D amplifier with digital inputs. Verify compatibility with the 10 V to 18 V supply range and 3.6 Ohm load impedance. Consider the HTSSOP-28 package constraints and the -25°C to +85°C operating temperature range. Evaluate the need for the specific 20 dB or 26 dB gain configuration against system requirements.
Part Context
This part belongs to the BD54 series of audio ICs from ROHM Semiconductor. It is categorized under Audio Amplifiers and specifically designed as a Class-D audio power amplifier. The manufacturer identifies it within the broader scope of Audio ICs, targeting high-power stereo speaker applications.
